alloc_validate_connector(9)

📦 version 7.3.1, in nixpkgs unstable

💅 alloc_validate_connector(9) — like, the connector-builder for event_property_validate() tests ✨

okay so bestie, welcome to the alloc_validate_connector(9) page from the Kernel API Manual 🎀 this one's a little helper that spins up a fake connector so the HDCP test suite has something to poke at. it's giving "supporting cast member who absolutely carries the scene" energy, ngl 💖

🌸 NAME 🌸

alloc_validate_connector — the connector for event_property_validate() tests 👑

🦋 SYNOPSIS 🦋

struct amdgpu_dm_connector * alloc_validate_connector (struct kunit
*test , unsigned int index , enum drm_connector_status status , bool
with_state );

that's the whole signature, no cap. four args in, one shiny struct amdgpu_dm_connector * out 🫶

✨ ARGUMENTS ✨

  • test — the KUnit test context, used for the managed allocation. it's the one holding the bag so nothing leaks 😌
  • index — the drm connector index you want assigned. you pick it, it wears it 💅
  • status — the drm connector detection status to assign. gotta tell the fake connector how it's feeling 🩺
  • with_state — whether to attach a zeroed drm_connector_state. yes please = a state gets bolted on, all zeroed out ✨

💜 DESCRIPTION 💜

so what it actually does: it allocates an amdgpu_dm_connector that's sufficient for the traversal that happens inside event_property_validate. that's the whole job, and it does it slayfully 👑

here's the tea though — mod_hdcp_query_display has no active display, so it bails out early 😭 and because it returns early, it leaves the pre-set HDCP_OFF query completely untouched. like, not even a little smudge. iconic behaviour, honestly 🧚

no active display → early return → HDCP_OFF query stays exactly as it was set. that's the entire bit, and it's lowkey perfect 🌈
